[PATCH 0/5] Follow-up on meson

[marcandre.lureau-H+wXaHxf7aLQT0dZR+AlfA]

From: Marc-André Lureau <marcandre.lureau-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

Hi,

Some v4 patches of the series "Add meson subsystem" were pushed, while v5 and v6
were posted on the list. Here is the remaining changes I have on top of
upstream. There are a few misc fixes, and the last patch removes the
Makefile-based system, while keeping the traditional make all/check/install/clean
interface to ease the transition.

Marc-André Lureau (5):
  meson: fix -Wall warning
  meson: do not assume python is installed, skip tests
  meson: increase default timeout for tests
  travis: install meson
  build-sys: replace makefiles to wrap meson/ninja

[PATCH 1/5] meson: fix -Wall warning

From: Marc-André Lureau <marcandre.lureau-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

Meson already handles Wall via the built-in warning_level option.

I'd prefer to also convert the Travis scripts to directly invoke meson
rather than going through the Makefile.

Ah, yeah, I guess we do.  And I was recently reminded that
travis-ci.org is shutting down.  I'm confused by the suggested
travis-ci.com move, so I'll probably just move to Gitlab's CI
instead.

So let's just leave it as is until then.

[PATCH 5/5] build-sys: replace makefiles to wrap meson/ninja

[marcandre.lureau-H+wXaHxf7aLQT0dZR+AlfA]

From: Marc-André Lureau <marcandre.lureau-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

This avoids maintaining two build systems, and update the documentation.

Makefile now wrap meson, so that make all/check/checkm/clean/install
continue working as they used to.

+Building
+--------
+
+This project is built with meson. See the manual for detailed usages:
+https://mesonbuild.com/Running-Meson.html
+
+In short, from the source directory, you can configure, build and test the
+project with those commands:
+$ meson builddir
+$ ninja -C builddir
+$ ninja -C builddir test
+
+For convenience, a Makefile wraps meson for you with the regular "make", "make
+check" and "make install" targets. Although further build tweaking will require
+you to invoke meson manually.

Sorry I've neglected this so long.  I finally got around to lookup up
a cheatsheet for how to use meson "natively" to understand this
better.

Couple of issues with this path though:

First, it no longer applies clean due to some added tests.  Can you
rebase please.

> +checkm:
> +	WITH_VALGRIND=1 meson test -C $(BUILD_DIR) -v

Second, the valgrind stuff doesn't seem to work.  I tried
"WITH_VALGRIND=1 meson test" and it completes much to fast to actually
be using valgrind.  Also it doesn't give any error if valgrind isn't
installed.

It's also not ideal that the output from "meson test" is trivial with
all the content now in the meson log file.  Assuming we can sort out
this first part, would you be willing to help convert the existing
testsuite / testrunner to be more "meson native" so we can improve
that?
